I'm preparing an image for download based on Raspbian. I can resize the partition manually using raspi-config. However, I'd prefer this to be automatic during first boot (maybe with a timeout for cancelling if such is possible).

Apparently BerryBoot is able to do this automatically- would appreciate a hint how this is done.

  1. make yourself a script that deletes or disables itself after first run (init for background or .profile for foreground)
grep -v custom_script.sh ~/.profile > ~/.profile.new && mv ~/.profile.new ~/.profile
  1. extract the bits you want from raspi-config (line 36 to to 116)
> file $(which raspi-config)
/usr/bin/raspi-config: POSIX shell script, ASCII text executable
  • Could you elaborate how the script would disable/delete itself?
